PFAS in Touillon's tap water: under 2.5 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 2.5 ng/L, 5 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.
Sample taken in Arrans, on the same distribution network as Touillon (SIAEP DE SAVOISY). The health authority samples one tap per network; a network carries the same treated water everywhere.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
The lab detects each of the four substances from 0.5 to 1 ng/L upward. None reached that limit, so their total is below 2.5 ng/L rather than zero.

Frequently asked questions
Is tap water in Touillon safe to drink?
Yes. At the check on 24 March 2026, the tap water in Touillon was within every limit tested. “Confirmation de la présence d'anthraquinone et d’Hydrocarbures Polycycliques Aromatiques (HAP) à ce point de prélèvement (origine : dégradation des canalisations). Teneurs relativement faibles n’induisant pas de restrictions d’usage de l’eau. Plan d’actions à mettre en œuvre pour limiter la présence de ces composés.”
How high are PFAS levels in Touillon's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in Touillon also meet the strictest limits in Europe?
As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 2.5 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
